Mountain bike tops cover a wider range of conditions and demands than road cycling apparel. You need shoulder mobility for technical handling, protection from the elements on exposed trails, and ventilation that handles the intensity of steep climbing. The subcategories here are distinct: jerseys for active riding, jackets that seal out rain and wind, baselayers for thermal management, and post-ride tops for when you’re off the bike. Getting the layering right — knowing what to wear under a winter jacket versus what you need for a dry summer trail — is what separates a comfortable ride from a suffer fest.

The heaviest hitters in the collection are from Assos’s Tactica line, their purpose-built mountain bike range. The T5 Winter Jacket handles cold-weather trail riding, the T5 Rain Jacket is built for wet conditions, and the GTO long sleeves cover the shoulder-season riding in between. Café du Cycliste fills out the baselayer side with the Judith and Liliane series — clean, performance-oriented underlayers that work across seasons. Bianchi Milano rounds out the collection with casual fan tees and baselayers for time off the bike.
